Description

Overlapping shading security stamp

Technical field

The utility model relates to a kind of overlapping shading security stamp.

Background technology

At present, the illegal activity of carving seal privately often takes place, and main cause is because traditional seal is too simple, only is carved with name or organization and simple pattern, does not have any antiforge function.People have begun to attempt using the anti-counterfeiting technology of seal, disclose a kind of security stamp such as Chinese patent CN2208492Y, on the chapter face of this seal printed words and pattern are arranged, and are superimposed with at random the bar groove on printed words and the pattern.This seal has certain antiforge function, but randomness is not had operability by force.

The utility model content

Technical problem to be solved in the utility model be propose a kind of can be according to user's wish overlapping shading security stamp design, strong security.

Technical scheme provided by the utility model is: a kind of Anti-fake stamp with overlapped shade, this seal includes the seal face, and literal or pattern are arranged on the seal face, also is provided with false proof shading on the whole or part of this seal face, this shading and literal or pattern stack.

Described literal or pattern with shading stack place be hollow out.

Described shading is that the pattern of dot matrix is or/and literal.

The utility model has the following advantages: be provided with shading at seal, shading can select according to the regulatory requirement of different industries, increases the seriousness of trade management; Shading adopts the dot matrix pattern or/and literal, and pattern or literal itself can adopt gray scale, the multi-level processing, improves antifalse effect.

Fig. 2 is another kind of embodiment of the present utility model;

Wherein: 1: seal face 2: literal 3: pattern 4: shading 5: numeral

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.

A kind of Anti-fake stamp with overlapped shade as shown in Figure 1, this seal includes seal face 1, and literal 2 and pattern 3 are arranged on the seal face 1, the part of this seal face is provided with digital anti-counterfeiting shading 4, this shading 4 and literal 2 and pattern 3 stacks, this stack place is hollow out, this shading 4 forms for dot matrix.

Another kind of seal as shown in Figure 2 has literal 2 and numeral 5 on the seal face 1, literal 2 and numeral 5 stacks; Also be provided with pattern anti-fake shading 4 on the part, this shading 4 and numeral 5 stacks, the stack of two places is hollow out; This shading 4 is irregular lattice structure.

The utility model adopts advanced graph technology to realize, at first adopts graphic design software to generate the figure of some irregular size and shapes, and forms needed pattern as the shading figure of seal with these figures.With PaintShop shading figure is carried out gray scale again and process, the gray scale of figure can be multi-level.Cover required seal literal or numeral etc. at the shading figure that handles well again, produce with photosensitive seal technology then and get final product after seal infiltrates photosensitive oil.

Because the shading of made can be according to user's wish design, such as unit trade mark, head portrait, special figure or numeral etc., thereby very strong antifalse effect is arranged.The dot pattern formation of composition shading figure has not repeated and has certain antifalse effect through certain processing; The former figure of each piece seal is divided into the two-stage template to be given administrative department to file to be convenient to management; Adopt and to carry out the true and false between the seal of advanced seal comparison system with the template of administrative department and seal and compare.
